I have an incredible fun at this level, as usual for me when it's all about solving a puzzle.
I just found a break through and reach target for first time now. Let's optimize...
Got it! Now to be honest, I didn't notice the difference between my 2 off route and the winning route, so I could probably not re-do it.
I was stuck at 146s, for very long. Today I found something better, but I am still 2 off. Who would think there are so many options in such a small space.
